Question

Use the distance formula to find the distance between

(-5, 6) and (8,4). Round to the nearest tenth if
necessary.

Answer 1

13.2

Explanation:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)\\\\(-5,6)\quad\implies\quad x_1=-5\,,\ y_1=6\\\\(8,4)\quad\implies\quad x_2=8\,,\ y_2=4\\\\\\d=√((8+5)^2+(4-6)^2)= √(13^2+(-2)^2)=√(169+4)=√(173)\approx13.2`
